The following information is regarding TuneCore's Publishing Administration service
Yes. Royalties from streams is the fastest growing revenue source for songwriters.
Depending on whether the streaming service is Interactive or Non-Interactive, there may be 1 or 2 royalty streams payable.
An Interactive Streaming Service means the user can choose his/her songs, stop, go backwards, go forward, create custom playlists, etc., with no restrictions. This type of service will generate 2 royalty streams: (1) a performance royalty, collected by your PRO / global rights performing society, and (2) a mechanical streaming royalty, collected by TuneCore Publishing Administration.
A Non-Interactive Streaming Service means the user cannot pick songs, create playlists, go backwards, see what song is playing next, etc. Think of it like traditional radio. This type of service will generate only 1 royalty stream: a performance royalty which is collected by your PRO in the US or by TuneCore Publishing Administration outside of the US.
